Income Taxes and the Consumption Schedule ● government purchases of goods and services total spending directly through the G component of C + I + G + (X - IM). ● taxes total spending indirectly by lowering disposable income and, thus, reducing the C component of C + I + G + (X - IM).

The Multiplier Revisited ● Multipliers for Tax Policy ♦ If G and T increase

The Multiplier Revisited ● Multipliers for Tax Policy ♦ If G and T increase by the same amount, the effects do not cancel out. ■ G GDP ■ T GDP ■Because G’s multiplier is larger, the net effect will be an increase in GDP. Copyright© 2003 South-Western/Thomson Learning. All rights reserved.

The Multiplier Revisited ● Moral: Fiscal policies that keep the deficit (G - T)

The Multiplier Revisited ● Moral: Fiscal policies that keep the deficit (G - T) constant do not keep AD constant. ♦ If spending increases are financed by tax increases, the economy will expand. ♦ If tax cuts are financed by spending cuts, the economy will contract.

Planning Contractionary Fiscal Policy ● Note that the self-adjusting mechanism will eventually perform the same task, but at the cost of more inflation than will occur if the government succeeds in reducing AD. Copyright© 2003 South-Western/Thomson Learning. All rights reserved.

The Choice Between Spending and Tax Policy ● The choice between G and T

The Choice Between Spending and Tax Policy ● The choice between G and T reflects a difference in opinion about the desirable size of the government sector. ♦ Advocates of small government prefer: ■To lower T in order to stimulate output ■To lower G to control inflation ♦ Advocates of big government prefer: ■There is nothing about an activist fiscal policy that implies a preference for big government.

Some Harsh Realities ● A fiscal policy planner’s job is not simple. ♦ Economic variables change continuously. ♦ The “policy target” is constantly moving. ♦ Economists have only an uncertain knowledge of the value of the multiplier and the fullemployment level of GDP. ♦ Forecasts are uncertain and policies take time to work.

Algebraic Treatment ● Multiplier for G, I, a, or (X - IM) with variable taxes = 1 1 - b(1 - t). ● The higher the rate of variable taxation, the lower the multiplier. Copyright© 2003 South-Western/Thomson Learning. All rights reserved.
